Specification of Letters Patent. Pa Application filed June 28, 1912.Serial 0. 706,411.

To all whom z't may concern Be it known. that we, GEORGE R. W. Ron.-ERTS and HARRY Hoorns SEEL ,.c t1zens of the United States, and.residents of Alameda, in the county of Alameda and State of California,have invented certain new and useful Improvements in Flu1d- Actu, the'followlng 1s a ated Gongs, of which specification.

Our present invention relates to fluid acfact any other vehicle whichhas an air brake system or is capable of carrying a supply of fluidunder pressure. i

The object of'our'invention is to provide inexpensive meanswhereby tocontinuously sound a gong without effort on the part of the operatorsubsequentto the opening of a valve for thepurposeof starting theactuation. H

In the accompanying drawing which illustrates our invention inyde'tail,Figure 1 is a side elevation, partly broken away and in section, of agong and sounding means coni structed in accordance with our 'invention;Fig. 2' is a partial central verticalsection through the device andtaken substantially on the line 22 of Fig. 1; Fig. 3 is a detailvertical section through one of the impulse after described, are adaptedto engage in' members or buckets, taken substantially on the line 33 ofFig. 4; and Fig. 4 is a detail cross section through the same takensubstantially on the line 4-4: of Fig. 3.

Referring now to these figures, we provide a hell or gong Ahaving on itsinner surface adjacent its peripheral edge an enlargement a which thestrikers, to be herein-- the course of their travel. The bell or gong Ais centrally secured by means of a thread ed connection with one reducedend 5 of lts stem B, the opposite reduced end I)" of which is securelyheld in the lower apertured end of the depending V-shaped portion 0 of abracket C, said bracket including an upper plate 0 extendinghorizontally above the hell or gong A and adapted to be secured, forinstance, by bolts or like fastening members as shown, to the platform Dof a street railway caror other vehicle in connection with which thecontinuously ringing gong is desired to be used.

yThe intermediate portion 6 of the stem Bfforms a bearing for thestriker which, for the purposes of our present invention, we prefer tobe of a rotatory character and to comprise hub-portion e which ismountedd rectly upon the bearing 6 and, a spider wheel 6" which is supported bythe hubs,

and from which in turn project the radial striker arms E of which theremaybeone or more. Each ofthese striker arms, which i Fig. 2 that thestriker -ring e is in substane tially the same; plane withthe projectiona of the gong A so t-hatin the rotatory movementof the'parts, saidprojection will be the several striker arms. e V

, The/spider wheel 6 is preferably prosuccessively engaged by thestriker rings of circular series of impulse members or buckets F, thesebuckets being of the par ticular construction shown in Figs. 8 and 4t,

and being adapted to receive a jet of fluid for the purpose of causingrotation of the striker with which they have connection as beforedescribed.

Secured beneath the plate 0" forming part of the bracket '0, anddepending from an opening therein, is a valve casing Gr, hav ingchambers g, g',from the latter of which depends a nozzle 9 this nozzleb'eing tangential to the impulse members or buckets 1 tented Dec. 1 *7,

vided wit-h a rim f, such as shown in orderi i that the same may beadapted tosupport a F, as-Jshown particularly'in Fig. 1. With the otherchamber 9 communicates an inlet pipe H, which in the case of a streetrailway car, may lead from a suit-able part of the brake system andthussupply operating fluid, or in the case of a vehicle not equippedwith means for supplying air, it may lead from a storage tank carried bythe vehicle. The valve chambers g and g are separated by a diaphragm inwhich is formed an opening surrounded by a valve seat and adapted toreceive thereagainst the conical valve 9 the upper portion of the stemof which projects through the before-mentioned opening in the bracketplate c and terminates slightly below the vehicle platform D. The

lower portion of the stem or valve g jextends downwardly within a guideformed in the removable plug g, and around this portion of the saidvalve stem is coiled a spring g whichis compressed between the lowerface of the valve and the said plug 9 in order to normally hold thevalve upwardly against the seat. In order that the valve may beconveniently opened for the admission of the fluid under pressure, weprefer ably provide a foot pedal J which is movable downwardly within aguide j secured within an opening in the car platform D. Thus the lowerend of the pedal J may engage the upper end of the valve stem, wherebylowering movement of the said pedal causes lowering movement of thevalve to its open position.

Thus it will be seen that the means which we have carefully explainedwill continuously ring a gong with only an initial efiort required onthe part of the operator to open the valve, and that the parts requirebut little change in order to adapt them to actuate a gong sounded bymeans of a swinging hammer instead of a rotatory striker, as at presentshown, and, in fact, many other types of gongs now in use. It will befurther seen that our invention possesses both strength and durability,and is generally free from parts which are likely to get out of order.

We claim 1. The combination of a gong having a bucket wheel, a strikercarried by the bucket wheel, a main support, a bracket depending fromthe said main support and carrying the gong, a foot pedal mountedthrough the main support, a valve casing mounted in the bracket andhaving a nozzle adapted to propel an actuating fluid against the saidbucket wheel, and a valve member within the said valve casing and havingan upwardly projecting stem beneath the foot pedal.

2. The combination with a gong having a striker, of a fluid actuatedrotor connected to the striker, a bracket member having a dependingportion on which said gong and its striker are supported and alsoprovided with an upper portion extending above the gong, a valve casingsecured to said upper portion of said bracket and having an inlet at oneside, a nozzle projecting from the opposite side of said valve casingand arranged to deliver an actuating fluid to said impulse members, andan upwardly seating spring controlled valve withinthe casing between thesaid inlet and the said nozzle and having an upwardly projecting stemextending above the valve casing and above the upper portion of thebracket, for the purpose described.
